guys i need an error-free way of keeping name value pairs in a regular c# string. i am quite busy, i dont think i am able to come up with the best algorithm now. what i want is two methods one to add a name-value pair to the string, the other is to get the value of that name.
Thanks for your help.
all my name-value pairs will in one string like a query string in url. is that what it comes to? i couldnt see it right away but i am busy too :)
dont try to answer to a busy guy if you are busy your self too :)
Following from http://www.albahari.com/nutshell/ch24.aspx
Extracting “name = value” pairs (one per line):
string r = @"(?m)^\s*(?'name'\w+)\s*=\s*(?'value'.*)\s*(?=\r?$)";
string text =
@"id = 3
secure = true
timeout = 30";
foreach (Match m in Regex.Matches (text, r))
Console.WriteLine (m.Groups["name"] + " is " + m.Groups["value"]);id is 3
secure is true
timeout is 30
He guys, thanks! I'm learning a lot here. :)
DdoubleD you're very active I like your way, keep it up.

Unfortunately i can't add to your reputation more than once a day.
By the way this albahari guy and i know each other, i am going to translate one of his tutorials(threading) into Turkish, we already made the deal but he said he is going to renew the tutorial, so i am waiting for him to complete.

i am also active man, where is my reputation? the one who asks the quality question is valuable as the one who answers properly right?
